Draining the float chamber of the carburetor
Following every wet-cleaning procedure, the float chamber of the carburetor
should be drained in order to remove any water that may have penetrated into
it. Water in the float chamber leads to engine malfunction.
Make sure you do this while the engine is cold. Close the fuel tap and place a
cloth under the carburetor, which is capable of absorbing the leaking fuel.
250 SX-F:
Unscrew the plug
[1]
and clean it with compressed air. Then, mount
the plug together with the gasket, open the fuel tap, and check the float chamber
for leaks.
450 SX-F:
Put the end of the hose that leads downward behind the engine
into an appropriate container.
Open the drain plug
[2]
, turning it counterclockwise a few times, and let the
fuel drain from the float chamber.
Then tighten the drain plug and open the fuel tap.
– Fuel is easily flammable and toxic. When handling fuel, be sure to exercise
the utmost caution. Never perform any work on the fuel system near open
flames or burning cigarettes.
– Always allow the engine to cool off first. Immediately clean up any fuel
which may have been spilled. Materials saturated with fuel are also easily
flammable. In case you ingested fuel or fuel splashed into your eyes, consult
a doctor immediately.
– Dispose of the fuel properly.
Checking the engine oil level
The engine oil level can be checked with the engine either warm or cold. Place
the motorcycle in an upright position and on a horizontal surface (not on the
side stand).
If the engine is cold, the engine oil must be visible at the lower edge of the
inspection glass
[A]
.
If the engine is warm, the engine oil must be visible up to the upper edge of
the inspection glass
[B]
.
Replenish the engine oil, if necessary.
Insufficient amounts of or low-grade engine oil lead to premature wear in the
engine.
